i ANTISKIDDING DEVICE FOR VEHICLE-WHEELS.

Specification of Letters Patent.

Patented June 30, 1914.

Application filed January 20, 1914. Serial No. 813.253.

1 clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

Th's invention relates to new and useful improvements in anti-skiddin devices for use in connection with automo bile tires and other vehicle wheels and the object in view is to produce a simple and etlicient device of this nature which may be easily and vquickly clamped about the tire and rim when desired for immediate use.

My invention comprises various details of .construction and combinations and arrangements of arts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.

,1 illustrate my invention in the accompanying drawings, in which Figure 1 .is a side elevation showing the application of my device to the tire and l'llh of a wheel. Fig. 2 is a cross sectional vie on line 22 of Fig. 1, and Fig. 3 is a detail perspective view. I p

Reference now being had to the details of the drawings by letter, A designates the rim of a wheel, and B 'desi 'nates a pneumatic tireheld to the clenc er member C upon the rim. A plate, designated by letter E, is provided with lugs E which are adapted to engage the opposite sides of the rim, as shown in the drawings, and other lugs, designated by letter E and bent in the opposite direction, are providedowith slots F in which the rod H is adapted to have a movement. Said rod is mounted in the flanges K of the lever K, and headed pins, designated by letter N, are fastened to said flanges and pass through apertures in the links 0, which latter are apertured as at O for the reception of the link Q, and hook Q, which are secured one to each end of the chain R. A plate J havingapertures therein for the reception of the links of the chain is adapted to be held by the latter against.

the tread surface of the tire when the device is adjusted for use upon a wheel. A coiled spring, designated by letter T, has one end T caught over the rod H and said spring bears against the surface of the plate E.

In applying the device to the rim of a wheel, a plate E is placed against the inner marginal edge of the rim and the chain edit nected to the links in the manner shown, after which the lever is swun to the posi tion shown in Fig. 1 of the E as the lever swings it is fulcrumed upon the rod H, which latter bears yieldingly against the spring T, while the link pivotally'connected to the rivet N swing with the lever and, after the pivotal points between the lever and said rivets pass by the rod H, the spring will buckle and draw the lever against the inner marginal edge of the rim of the Wheel. By this movement, hich ives a toggle joint action to the chain,- the iatter will be drawn taut and the plate J, through which the chain passes, will be held tfrict-ion'ally against the tread surface of the tire. A reverse swinging movement of the lever will slacken the chain and allow the same to be readily removed. By having the rivets upon which excessive strain comes, shouldered as shown, the connection will be rendered of sufficient strength to withstand- .chain are adapted to be fastened, as set forth.

2. An anti-skidding device for vehicle wheels comprising a plate having lugs-projecting therefrom and designed to engage over the edges of the inner periphery of the rim, slotted lugs struck up from said plate and projecting in the opposite direction, a

rawings and,

rod movable within said slots, a spring intel-posed between the rod and plate, a lever in which said rod is mounted, a chain adapted to be passed about thetire of the-wheel,-

and'links pivoted to said lever and to which" the ends of the chain are eonneated, set forth,

3. An anti-skidding device for vehicle "wheels comprising :1 plate. lnivii'ig lugs projei-ting therefrom and designed to engage over the edges of the inner periphery of the rim. slotted lngsstrnck up from said plate and projecting in the opposite jlirection. a rod .nomhle Within said slots a spring interpmed between the rod and plate, n lever in which said rod is mounted, headed rivets fastened to said lever links pivotall gr connected to said rivets and having n'peitni'es therein, a chain, the ends of Wllif'l. are :uhmted to he fiistened in said apeitnree, {1S set forth.

4. An :llllQl-Flklddillfif devive for vehicle whee comprising a plate having lug-a pro jecting therefrom and designed to engage over the edges of the inner periphery of the rim, slotted lugs struck up from said plate and projecting in the opposite direction, a rod-movable within said slots, a spring in lC'l'POSGL'l between the rod and plate, u lever having two arms, the ends of which are fastened to the ends of said rod, headd rivets fastened one to each of said arms, :1 crosspieoo connecting said arms, links pivotally mounted upon said headed rivets, and a chain, the ends of which are adapted to he lnntened one to each of said apertured links, as set forth.

in tcstimony whereof I hereunto alhx my signature in presence of two Wil'IlQSSBS.
